- In order to reduce the excessive numerical dissipation which is induced when a grid system is not aligned with a discontinuity, a new spatial treatment of cell-interface fluxes is introduced. The M-AUSMPW+ in this paper possesses an additional procedure of re-defining transferred properties at a cell-interface based on AUSMPW+ , and it shows a complete monotonic property regardless of sonic point location. The newly defined transferred property could eliminate numerical dissipation effectively in non-flow aligned grid system of multi-dimensional flows.
